-----------------------------------------

hi [~gtCarrera], [~varun_saxena]  & [~sjlee0],
Hope one of you can do the initial review for the approach mentioned here in the absence of
[~djp], So that if the basic approach is fine then will proceed ahead with other jira's like
YARN-3880 and in parallel keep on correcting this jira.

> Currently to add new timeline event/ entity in RM side, one has to add a method in publisher
and a method in handler and create a new event class which looks cumbersome and redundant.
also further all the events might not be required to be published in V1 & V2. So adopting
the approach similar to what was adopted in YARN-3045(NM side)
